Additional Information

Adam Goodworth, PhD, PE, is a biomechanics specialist providing expert opinions on • Claimed Injuries and injury mechanisms • Vehicle Occupant Kinematics • Event Data Recorder (EDR) • Work and Recreation Accidents (eg, slip, trip, falls) • Seat Belt Function • Fetus injuries Dr. Goodworth is a Professional Engineer in California (# M40242), an ACTAR Accredited Traffic Accident Reconstructionist (# 2225), trained in EDR interpretation (“black box”), and active in research of restraint systems and occupant kinematics. Dr. Goodworth can perform vehicle Inspections and site investigations in California and across the US. Dr. Goodworth has been a Professor for over 13 years. Currently, a full tenured Professor at Westmont College in Santa Barbara, CA, Dr. Goodworth has over 50 peer-reviewed journal and conference publications. His research has been funded by the National Science Foundation, National Institutes of Health, and Department of Defense. His teaching includes Biomechanics, Causes of Injury, Research, Human Motor Control, Engineering Materials, and Control Systems. Dr. Goodworth takes pride in explaining technical topics in a clear and simple manner with visuals and illustrations. He teaches undergraduate students where effective COMMUNICATION of technical topics is required. He is a member of the American Academy of Forensic Sciences, Society of Automotive Engineering, and International Society for Posture and Gait Research. He is the Director of the Biomechanics & Balance Lab at Westmont College where he tests seat belts and analyzes kinematics. Consultants with Dr. Goodworth include - William Broadhead and Ted Zinke (with 90+ yrs of combined experience) at ASR in expert analyses of airbags seat belts, and sensor performance; and Dr. Jacqueline Paver, 40+ yrs biomechanics experience, Center for Injury Research.
